I've had a boy in care for 3 years who eats more than the other 4 children put together. I've been telling his parents that I don't make any profit from them at all. He always eats 2 or 3 servings of meat, veggies and bread items and would eat all the fruit in my fridge daily if I let him. And he's a skinny little kid! Since I give him a very balanced diet daily I let him have extra bread and veggie items since they are not as expensive as the 4th servings of meat & fruit, you know? Although I serve all organically grown veggies and fruit so neither are cheap, but the fruit prices are insane. Also, I've cut him off after 3rds for the past few years. I think that's enough food for him and he is still growing and thriving.
